First County FCU appeared on the leak site operated by the qilin ransomware group on April 25, 2026. The group claims to have exfiltrated internal files during a ransomware attack. The number of people affected remains unknown, and no further details on the volume or contents of the data have been made public.
Ransomware operators continue to publish stolen data from financial-sector targets as a pressure tactic. Listings of this kind raise questions for members of credit unions about how their personal and financial records may have been handled.
Inside the incident
The only confirmed public information is the April 25, 2026 listing on the qilin site. The group states that internal files were taken. No independent confirmation of the data theft, the attack method, or the scale of the operation has been released. The number of individuals whose information may be involved is not disclosed.
Inside qilin
Qilin is a ransomware group that maintains a public leak site and follows a double-extortion model in which data is both encrypted and threatened with publication. The group has been linked to multiple incidents across different industries in recent years. Its listings represent claims by the operators rather than verified statements of fact.
Who is First County FCU?
First County FCU is a credit union, a member-owned financial institution that provides banking, lending, and account services. Organizations of this type routinely process personal identifiers, account numbers, transaction histories, and loan documentation. A breach at such an entity can expose records that are directly tied to members' financial lives.
The information in question
The listing refers only to “internal files.” No specific categories of data have been confirmed. Credit unions commonly hold Social Security numbers, account credentials, addresses, and financial histories, but the exact contents of the claimed exfiltration remain unconfirmed.
What's at stake
Individuals whose records appear in stolen internal files face the possibility of identity theft or account fraud. Credit unions hold data that can be used to open new accounts or access existing ones. For the organization, the incident may trigger regulatory review and increased scrutiny of its security controls, though the precise operational impact has not been stated.
What to do if you're exposed
Monitor account statements and credit reports for unusual activity. Place fraud alerts or credit freezes with major bureaus if concerned about misuse of personal identifiers. Change passwords for any accounts linked to the credit union and enable multi-factor authentication where available.
- Review recent transactions on all linked accounts.
- Contact the credit union directly for any official guidance it issues.
- Run a free exposure scan of your email address against known breach data to check for additional appearances.

Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
